A DEBATE ABOUT the power in Washington of the pro-Israel lobby is underway, after Rep. Ilhan Omar, D-Minn., responded sharply to reports that Republican leader Kevin McCarthy was targeting both Omar and fellow Muslim Rep. Rashida Tlaib, a Democrat from Michigan.

Omar quoted rap lyrics — “It’s all about the Benjamins baby” — to suggest McCarthy’s move was driven by the lobby’s prolific spending. Asked specifically who she was referring to, Omar responded, “AIPAC!”

The debate over the influence of pro-Israel groups could be informed by an investigation by Al Jazeera, in which an undercover reporter infiltrated the Israel Project, a Washington-based group, and secretly recorded conversations about political strategy and influence over a six-month period in 2016. That investigation, however, was never aired by the network — suppressed by pressure from the pro-Israel lobby.
